@noWaifuNoLaifu it's a Japanese manga and anime...not Chinese. The full name "Tengen Toppa Gurren Lagann" most closely translates to "Heaven Piercing Gurren Lagann" I won't break those down in the title because it is the name of the mech. The smaller mech's names translate as follows:
Gurren- Crimson Lotus
Lagann- Enveloping Face
